TOBW(1)TOBW(1)NAMEtobw - Convert a 24 bit RLE file to eight bits of gray scale value.
SYNOPSIStobw [ -t ] [ -o outfile ] [ infile ]
DESCRIPTION
Tobw converts an image with 24 bit pixel values (eight bits each of
red, green and blue) to eight bits of grayscale information. The NTSC
Y transform is used. If the -t flag is given, then the monochrome
pixel values are replicated on all three output channels (otherwise,
just one channel of eight bit data is produced). If no input file is
specified, tobw reads from stdin. If no output file is specified with
-o, it writes the result to stdout.
